I know that I have pushed it too far when I'm at home, finish in the restroom, and look for hand rails because my legs are so jacked up that I can't stand. Post up if you've been there! LOL! I love the pain, tells me that I'm putting in work. Just sucks for a few days.
Don't care if you do. This is not going to be another talk about Kenny's Cobalt thread. I know what my other car runs and I am proud of it. It might be hard for you to swallow that pill, but there are lots of 4 bangers that run 13s and better. SRT-4 Neons, Cobalt SS's, Saturn Sky Redline's and Evo's do it all the time.
When I lived at my parents house, I would drag my ass up the stairs with my arms.
As for getting off the toilet, I would lean all the way forward. Then push off my knees. Gotta get a little momentum, but it's always worked for me.
